Definitions

  • the present invention relates to a muscle stimulating apparatus.
  • Muscle stimulating apparatuses which comprise a plurality of electrodes which are applied to the skin and a pulse source which supplies to them a stream of pulses of suitable frequency, amplitude and waveform to stimulate muscles below the skin for the purposes of toning or exercising them.
  • One such apparatus is the Slendertone (Registered Trade Mark).
  • Multiple-channel muscle stimulators which have a number of pairs of electrodes to which a stimulating pulse train is applied. Where a number of pairs of electrodes is used the problem arises that by mis-use or incorrect connection of the electrodes to the pulse source, it is possible for undesirable effects to occur.
  • US 3851651 discloses a muscle stimulator according to the precharacterizing part of claim 1.
  • the multiple outputs are intended to enable different muscle groups to be stimulated at the same time from a common pulse source.
  • the disclosure is not concerned with electrode-pair interactions or the stimulation of muscles of the same muscle group.
  • One suitable form for the applied signals is bursts followed by spaces of lengths approximately equal to the bursts.
  • the leading edge of the envelope of each burst is rounded by the modulating means so that the burst surges to its maximum value.
  • One way of producing such a waveform with the present apparatus is to have a pulse generator which generates the pulses at a desired frequency (e.g. 100/Mn) and to amplitude modulate it with the output of a much lower frequency square waveform from an envelope timing generator and having a suitably rounded leading edge.
  • the resulting modulated pulse train is applied via an amplifier/buffer to the primary of an output transformer.
  • the output of the higher frequency pulse generator is also connected to a pulse counter and "One of N" decoder, where N is the desired number of outputs of the apparatus.
  • multiplexing circuitry suitable for deriving N separate pulse streams, one for each set of electrodes.
  • each set of electrodes may share a common return line and this can include a current limiting device such as a controlled current source to ensure that the maximum current is limited to a desirable and safe level.
  • the illustrated apparatus has a number of advantages. Because of the time division multiplex method of production of the pulse streams and the inclusion of the current limiting device, the pulses applied to each set of electrodes have a known and limited maximum energy content. The apparatus is incapable of providing peak voltages and currents beyond those supplied by the transformer and current limiting device, regardless of any accidental or deliberate cross connecting of any output electrode groups. Electrical interaction between electrodes of different sets when placed on the skin for the purpose of stimulation cannot occur because the pulse signals to each arrive at the electrodes at different times, therefore the effects of having signals present on all outputs simultaneously, which is mentioned above has caused interaction problems in the past, is eliminated.
  • the apparatus comprises a pulse generator 1 whose output is delivered by a delay circuit which provides a short delay to equalise delay times throughout the circuitry to a mixer 3 where the pulse stream D is amplitude modulated with a much lower frequency pulse waveform B.
  • This waveform B has an approximately 50 percent duty cycle and rounded positive-going edges and is derived from a lower frequency pulse generator 4 by an envelope shaper 5.
  • the output from mixer 3 is applied to the input of an amplifier and buffer 6 which drives the primary 7 of an output transformer 8.
  • pulse generator 1 The output of pulse generator 1 is also applied to the input of a pulse counter 9 whose outputs F to J each go high in succession to produce 4 streams of pulses as indicated at F to J in Figure 2 which go high in non-overlapping relation to one another and in synchronism with respective ones of 4 successive pulses of the pulse train E.
  • the pulse counter may, for example, comprise a 4-bit recycling counter whose outputs are connected to a "One-of-4" decoder.
  • potentiometers 11 to 14 Connected in parallel across the secondary 10 of transformer 8 are four potentiometers 11 to 14 associated with respective output terminals W-Z to which, in use, may be connected one electrode of each of 4 sets of electrodes which may be applied to the body of the user using suitable body pads.
  • the wipers of the potentiometers 11 to 14 are connected to the associated terminals W-Z via respective electronically operated switches 15 to 18 which are controlled by the individual ones of the outputs F to J of pulse counter 9.
  • These electronic switches may be of the opto-isolator type e.g. having a light emitting diode driven by the associated output of pulse counter 9 and a phototransistor constituting the controlled-conduction path. This, of course, serves to ensure that the circuitry connected to the body electrodes "floats" for isolation purposes.
  • the outputs W-Z may share a common return line 19 to the secondary 10 of the transformer and this may include a current limiting device 20 such as a constant current source to keep the pulsed currents at a desired value.
  • a current limiting device 20 such as a constant current source to keep the pulsed currents at a desired value.
  • each potentiometer 11-14 is shown connected to its associated output W-Z via an amplifier 21-24 and switch 15-18.
  • This arrangement of the amplifiers and switches is intended to be schematic in the corresponding part of Figure 3; the controlled element of each opto-isolator is a photo transistor 15-18 which when turned on shunts the collector to emitter circuit of an associated transistor 21-24 which corresponds to the amplifier in Figure 2.
  • These transistors 21-24 are suitably rated to handle the output voltage from transformer 8.
  • Figure 3 shows one possible implementation of the circuitry of Figure 1 using "556" timers, CD4000 series logic circuitry and opto-isolators.
  • suitable signal characteristics are as follows:-
